For HW01, I collaborated with Adan, who reviewed my code and provided valuable feedback. He pointed out that my variable names were meaningful and clear, my formatting was good, and all my methods were well-commented. He didn't find any issues with unused imports or warnings, and he didnt mention any obvious ways to make my logic more efficient.

The most challenging part for me was passing the unit tests for the getCount method, which was the only test that failed. While the existing tests are pretty comprehensive, I think they could still be improved by covering more cases and enhancing readability. Even though they cover the full range of HW1 functionality, there's always room for improvement by adding more diverse options.

One specific struggle I faced was an issue where I initially solved a problem by forcing all letters to uppercase, only to later realize that I needed to differentiate between uppercase and lowercase letters. That really did not help in the end. Despite these challenges, I’m proud of how clear and organized my code turned out, making it easy to follow and understand.
